2 SAFETY PRECAUTIONS - English
WARNING: These Safety Precautions are for your protection. They summarize precautionary
information from the references listed in Additional Safety Information section. Before performing any
installation or operating procedures, be sure to read and follow the safety precautions listed below as
well as all other manuals, material safety data sheets, labels, etc. Failure to observe Safety
Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS
Some welding, cutting and gouging precesses are noisy and require ear
protection. The arc, like the sun, emits ultraviolet (UV) and other radiation
and can injure skin and eyes. Hot metal can cause burns. Training in the
proper use of the processes and equipment is essential to prevent accidents.
Therefore:
1. Always wear safety glasses with side shields in any work area, even if welding helmets face
shields and goggles are also required.
2. Use a face shield fitted with the correct filter and cover plates to protect your eyes, face, neck
and ears from sparks and rays of the arc when operating or observing operations. Warn
bystanders not to watch the arc and not to expose themselves to the rays of the electric-arc or
hot metal.
3. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuffless trousers, high-topped
shoes and a welding helmet or cap for protection, to protect against arc rays and hot sparks or
hot metal. A flameproof apron may also be desirable as protection against radiated heat and
sparks.

US warnings
4. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and collars
should be kept buttoned and open pockets eliminated from the front of clothing.
5. Protect other personnel from arc rays and hot sparks with a suitable nonflammable partition or
curtains.
6. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot and
can fly far. Bystanders should also wear goggles over safety glasses.
FIRES AND EXPLOSIONS
Heat from flames and arcs can start fires. Hot slag or sparks can also cause
fires and explosions. Therefore:
1. Remove all combustible materials well away from the work area or cover the materials with a
protective nonflammable covering. Combusible materials include wood, clot, sawdust, liquid and
gas fuels, solvents, pants and coatings papper, etc.
2. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and cause a
hidden smoldering fire or fires on the floor below. Make certain that such openings are protected
from hot sparks and metal.
3. Do not weld, cut or perform other hot work until the workpiece has been completely cleaned so
that there are no substances on the workpiece which might produce flammable or toxic vapors.
Do not do hot work on closed containers. They may explode.
4. Have fire extinguishing equipment handy for instant use, such as a garden hose, water pail, sand
bucket, or portable fire extinguisher. Be sure you are trained in its use.
5. Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat
and create a fire hazard.
6. After completing operations, inspect the work area to make certain there are no hot sparks or hot
metal which could cause a later fire. Use fire watchers when necessary.
7. For additional information refer to NFPA Standard 51B, “Fire Prevention in Use of Cutting and
Welding Processes”, available from the National Fire Protection Association, Batterymarch Park,
Quincy, MA 02269.
ELECTRICAL SHOCK
Contact with live electrical parts and ground can cause severe injury or
death. DO NOT use AC welding current in damp areas, if movement is
confined, or if there is danger of falling. Therefore:
1. Be sure the power source frame (chassis) is connected to the ground system of the input power.
2. Connect the workpiece to a good electrical ground.
3. Connect the work cable to the workpiece. A poor or missing connection can expose you or others
to a fatal shock.
4. Use well-maintained equipment. Replace worn or damaged cables.
5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and power
source.
6. Make sure that all parts of your bady are insulated from work and from ground.
7. Do not stand directly on metal or the earth while working in tight quarters or a damp area; stand
on dry boards or an insulating platform and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 (listed on next page) for specific grounding
recommendations. Do not mistake the work lead for a ground cable.

US warnings
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding and cutting current
creates EMF around welding cables and welding machines.
Therefore:
1. Welders having pacemakers should consult their physician before welding. EMF may interfere
with some pacemakers.
2. Exposure to EMF may have other health effects which are unknown.
3. Welders should use the following procedures to minimize exposure to EMF:
a. Route the electrode and work cables together. Secure them with tape when possible.
b. Never coil the torch or work cable around your body.
c. Do not place your body between the torch and work cables. Route cables on the same side
of your body.
d. Connect the work cable to the workpiece as close as possible to the area being welded.
e. Keep welding power source and cables as far away from your body as possible.
FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in confined
spaces. Do not breathe fumes and gases. Shielding gases can cause
asphyxiation.
Therfore:
1. Always provide adequate ventilation in the work area by natural or mechanical means. Do not
weld, cut or gouge on materials such as galvanized steel, stainless steel, cooper, zinc, lead
beryllium or cadmium unless positive mechanical ventilation is provided. Do not breathe fumes
from these materials.
2. Do not operate near degreasing and spraying operations. The heat or arc can react with
chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other irritant gases.
3. If you develop momentary eye, nose or throat irritation while operating, this is an indication that
ventilation is not adequate. Stop work and take necessary steps to improve ventilation in the work
area. Do not continue to operate if physical discomfort persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation recommendations.
5. WARNING: This product when used for welding or cutting, produces fumes or gases which
contain chemicals known to the State of Californa to cause birth defects and in some cases
cancer (California Health & Safety Code §25249.5 et seq.)
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently release gas. Sudden
rupture of cylinder valve or relief device can injure or kill.
Therefore:
1. Use the proper gas for the process and use the proper pressure reducing regulator designed to
operate from the compressed gas cylinder. Do not use adaptors. Maintain hoses and fittings in
good condition. Follow manufacturer's operating instructions for mounting regulator to a
compressed gas cylinder.
2. Always secure cylinders in an upright position by chain or strap to suitable hand trucks,
undercarriages, benches, wall, post or racks. Never secure cylinders to work tables or fixtures
where they may become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have valve protection cap in place if regulator is
not connected. Secure and move cylinders by using suitable hand trucks.
4. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1, “Precations for Safe Handling of
Comporessed Gases in Cylinders”, which is available from Compressed Gas Association, 1235
Jefferson Davis Highway, Arlington, VA 22202.

Make sure the torch chosen is of the proper rating for the welding current to be
used, has the proper size and type of liner, the proper contact tip and the proper
guide tube.
9.2 Water connection
When connecting a water-cooled welding gun, the power source's main power
supply switch must be in the Off position and the cooling unit switch must be in
position “ELP/0”.
The wire feed unit with water connection is equipped with a detection system ELP
(ESAB Logic Pump) which checks that the water hoses are connected. When
connecting a water-cooled welding gun, the water pump starts.
Detection only works with power sources that are equipped with ELP.
US

bm33d1aa
9.3 Starting procedure
When the wire feed starts, the power source generates welding voltage.
If there is no welding current flow within three seconds, the power source switches the
welding voltage off. The wire feed continues until the welding gun's switch is switched
off.
9.4 Function explanations
Burnback time
Burnback time is a delay between the time when the wire starts to brake until the
time when the power source switches off the welding voltage. Too short burnback
time results in a long wire stickout after completion of welding, with a risk of the wire
being caught in the solidifying weld pool. Too long a burnback time results in a
shorter stickout, with increased risk of the arc striking back to the contact tip.
Slow run in
Slow run in start means that the wire is fed at low speed until it comes into electrical
contact with the workpiece and then the speed increases to the set speed.
2 stroke
With 2 stroke, the gas flow and wire feed start when the trigger switch is pressed in
and end when it is released.
4 stroke
With 4 stroke, the gas flow starts when the trigger switch is pressed in and the wire
feed starts when it is released. The welding process continues until the switch is
pressed in again, the wire feed stops and when the switch is released the gas stops
flowing.
Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
US
- 25 -
bm33d1aa
9.5 Wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder's pressure rollers. It is important that the
pressure is not too great.
Fig 1 Fig 2
To check that the feed pressure is set correctly, you can feed out the wire against
an insolated object, e.g. a piece of wood.
When you hold the gun approx. 0.2” (5 mm) from the piece of wood (fig. 1) the
feed rollers should slip.
If you hold the gun approx. 2” (50 mm) from the piece of wood, the wire should be
fed out and bend (fig. 2).
WHEN THE WIRE FEEDER IS CONNECTED TO THE POWER SOURCE, THE WORK
LEAD FROM THE POWER SOURCE IS CONNECTED TO THE WORK PIECE AND
THE POWER SOURCE IS ENERGICED, CLOSING THE TORCH TRIGGER WILL
CAUSE THE WELDING WIRE TO BECOME ELECTRICALLY HOT AND WILL CAUSE
THE DRIVE ROLLS TO TURN. KEEP FINGERS CLEAR!
Before threading welding wire, make sure the chisel point and burrs have been
removed from the end of the wire to prevent the wire from jamming in the torch
liner.

UNPROTECTED EYES OR START A FIRE. BODY CONTACT WITH A BARED
CABLE, CONNECTOR, OR UNCOVERED CONDUCTOR CAN SHOCK, POSSIBLY
FATALLY.
Wire feed unit
Check regularly to insure that the wire feed unit is not clogged with dirt.
Cleaning and replacement of the wire feed unit mechanism's worn parts should
take place at regular intervals in order to achieve trouble-free wire feed. Note
that if pre-tensioning is set too high, this can result in abnormal wear on the
pressure roller, feed roller and wire guide.
The brake hub
The hub is adjusted when delivered, if
readjustment is required, follow the instructions
below. Adjust the brake hub so that wire is slightly
slack when wire feed stops.
Adjusting the braking torque:
Turn the red handle to the locked position.
Insert a screwdriver into the springs in the hub.
Turn the springs clockwise to reduce the braking torque
Turn the springs counter clockwise to increase the braking torque.
NB: Turn both springs the same amount.
